I have been slacking recently on Validating pages. Does it really matter to search engines if there are a few errors on the site?
I would say that is probably best to have valid code. 1. You need to have cross browser compatibiliy 2. The search engines probably like clean code, but I'm not sure.
Code that is not properly validated can still rank very well. Matt Cutts had this to say a while back: I thin validation matters more in terms of: 1. User experience if it affects the way they can browse the page 2. Search engines only if it actually physically interferes with spidering. Dylan
I think he means xhtml validation..eh Dude as far as i can see you do-not need to have a valid coded page to get into google, although it helps a tiiiny bit.
